Shrub rose plant named `Captain Samuel Holland`

ABSTRACT

A new and distinct variety of shrub rose plant is provided which forms on an intermediate basis attractive fuchsia red blossoms that commonly are borne in clusters. The new variety exhibits a spreading and trailing growth habit with glossy foliage, and good winter hardiness. Resistance to pwodery mildew and blackspot has been observed. The new variety progpagates well by the use of softwood stem cuttings, and is well adapted for growing as colorful ornamentation in the landscape.

SUMMARY OF THE INVENTION

The new variety of shrub rose plant of the present invention was createdby artificial pollination during 1981 at the Central Experimental Farm,Ottawa, Ontario, Canada. The female parent (i.e., the seed parent) wasRosa kordesii×(Red Dawn×Suzanne), and the male parent (i.e., the pollenparent) was [(Rosa kordesii×(Red Dawn×Suzanne)×(Red Dawn×Suzanne)]. Eachof the named plants utilized in the breeding program was non-patented inthe United States. Selective study carried out at Ottawa, Ontario,Canada, resulted in the identification of a single plant of the newvariety.

It was found that the new variety of shrub rose plant of the presentinvention possesses the following combination of characteristics:

(a) exhibits a spreading and trailing growth habit with glossy foliage,

(b) forms in clusters attractive fuchsia red blossoms,

(c) propagates well by the use of softwood cuttings,

(d) exhibits a good winter hardiness, and

(e) is particularly well suited for growing in the landscape.

The rose plants can be grown well on their own roots out-of-doorswithout protection at L'Assomption, Quebec, Canada. The blossomscommonly appear on an intermediate basis. Resistance to powdery mildewand blackspot is exhibited.

The new variety well meets the needs of the horticultural industry. Itcan be grown to advantage as attractive ornamentation in parks, gardens,public areas, and residential landscapes. It is particularly well suitedfor growing in the landscape.

The characteristics of the new variety have been found to be homogenousand stable and have been shown to be strictly transmissible by asexualpropagation by the rooting of softwood stem cuttings and by tissueculture conducted at L'Assomption, Quebec, Canada.

The new variety has been named the Captain Samuel Holland variety.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs show, as nearly true as it is reasonablypossible to make the same in color illustrations of this character,typical specimens of plants and plant parts of the new variety. The roseplants of the new variety described herein were approximately 5 to 6years of age and were photographed during September 1993 while growingon their own roots at L'Assomption, Quebec, Canada.

DETAILED DESCRIPTION

The chart used in the identification of colors is that of The RoyalHorticultural Society (R.H.S. Colour Chart). Common color terms are tobe accorded their ordinary dictionary significance. The description isbased on the observation of 5 to 6 year-old plants of the new varietywhile being grown outdoors at L'Assomption, Quebec, Canada.

Class: Shrub.

Plant:

Height.--Approximately 1.5 to 1.8 meters on average.

Width.--Approximately 1 meter on average.

Habit.--Spreading and trailing.

Branches:

Color.--Young stems: medium green with a tinge of red. Mature stems:medium green.

Prickles.--Shape: slightly concave on the upper and under edges. Size:medium. Quantity: approximately 5 per 100 mm of stem on average.

Color.--Bright red when young and tan when mature.

Leaves: Compound and pinnate. stipules -- narrow and linear with erectauricles.

Petioles.--Medium green with a tinge of red when young and yellowishgreen when mature.

Petiolules.--very short.

Leaflets.--Number: commonly 5 or 7. Shape: oval to rounded base, someare uneven, with acute tip. Serration: single and irregular.

Color.--Adult foliage: initially a light yellow green approximatingGreen Group 137C on the upper surfaces and darkens as the leaves mature(as illustrated). The under surfaces of the leaves commonly are lighterin coloration (as illustrated). General appearance: glossy.

Rachis.--Smooth with very small prickles on the underside.

Inflorescence:

Number of flowers.--Usually 1 to 10 per stem.

Peduncle.--Erect, medium green when young and when mature, slightyglandular commonly 3 to 3.5 cm. in length, commonly bears no prickles.

Sepals.--Commonly 5 in number, extend beyond the bud on young buds,commonly include foliation, medium green with a tinge of red when youngand yellow green with a tinge of red when mature.

Buds.--Shape: pointed before the opening of the sepals, andprogressively becoming ovoid upon opening. Color upon opening: the outerpetals are deep pink.

Flower.--Shape: initially cup-shaped and subsequently assumes aflattened configuration (as illustrated). Diameter: approxiamtely 7 cmon average. Color (when blooming): deep fuchsia red, when youngapproaching Red-Purple Group 66B (but commonly with more red and lesspurple), on the upper surface, and lighter on the under surface,approaching Red-Purpple Group 66D. As the blossoms mature, thecoloration lightens (as illustrated). Fragrance: slight. Petal number:approximately 23 on average. Petal texture: velvety. Lasting quality:the blossoms commonly last approximately 5 to 7 days while present onthe plant under most growing conditions. Petals drop: the petals dropoff fairly cleanly. Anthers: gold in coloration. Pollen: light yellow incoloration. Filaments: yellow-green in coloration. Receptacle: ovoid inconfiguration, green in coloration, and generally female sterile.

Development:

Vegetation.--Intermediate vigor.

Blossoming.--Flowers heavily during June and on a continuous basis butto a lesser degree throughout the remainder of the season.

Hardiness.--Survives consistently without cover in Eastern Canada (Zone4, Quellet and Sherk, 1967).

Resistance to diseases.--Generally resistant to mildew and blackspot,some blackspot may be observed on the lower leaves at the end of theseason.

Preferred mode of propagation.--The use of softwood cuttings to produceself-rooted plants in recommended for the production of qualitycold-tolerant plants.
